CONTAINER Application. filed larch 7, 1929. Serial No. 345,044.

This invention relates to a container 7 adapted to be made from paper orsimilar material and primarily designed to contain li uid or semi-liquidcommodities. n handling such commodities as milk for instance,- the useof refilled glass bottles not only leaves much to be desired forsanitary reasons, but the handling of the bottles involves a great dealof labor and expense and many losses are incurred. 7

It is my purpose, therefore, to provide a sanitary container which maybe advantageously used for delivering milk or similar commodities to theconsumer, either from the milk wagon or from a store, a container whichis not likely to break or leak and which may be produced at such lowcost that it may be thrown away after it has been used once.

provide in a container of this character, various improved featureswhich will be more particularly explained in 'connection with theaccompanying drawings, illustrating one embodiment thereof. 7.

In the drawings:

- Figure 1 is a plan view of the blank from which the container is made.

Figure 2 is a perspective view of the con- 30 tainer completed, with twotop fla s open.

Figure 3 is a perspective view 0 the container with the top sealed. I V

Figure 4 is a sectional view of the lower part of the container, takenon the section line 4 of Figure 3. I

Figure 5 is a similar view taken on the section line 5 of Figure 3.

In its preferred form, the container is made from a single paper blankhaving five panels, 10, 11, 12, 13 and 14, adapted to be folded along'the lines 15, which may be creased for that purpose. Bottom flap 16, 17,18, 19 and 20 are integrally connected to the lower ends of therespectlve panels and are formed with creases 21, 22 and 23 to form foldlines.

In forming the container, the blank is first folded on the lines 15 toform the four walls of the container, with the panel 14 overlying thepanel 10 and pasted thereto. The, bottom It is also an object of myinvention-to downwardly therefrom and made up of fivev plies on one sideand four plies on the op posite side as shown in Figure 4, while theother two sides consist of three plies as shown in Figure 5.

Certain of the side panels, as the panels 12,

10 and 14, have respective top flaps 26, 27

and 28 integrally connected thereto and adapted to be successivelyfolded along the lines 29 to constitute a top with three layers. Theinner to layer 26 is formed with side strips 30 wh ch are foldeddownwardly on the' ines31 to lie against the sides 11 and 13, as shownin Figure 2. The to layer 27 is formed with a strip 32 which is foldedon the line 33 to lie against the side .12. The final top layer 28 isformed on three sides with strips 34 which are then folded on the lines35 to lie against the walls 11, 12 and '13 respectively.

'The inner top layer 26 is formedwith a comparatively large opening 36,the second top layer 27 is preferably formed with two small openings 37,while the final top layer 28 is imperforate.

In manufacturing the container as a commercial proposition, thecontainer blank will be stamped out and creased, then folded on thelines 15 and the panel 14 glued or pasted to the panel 10. The containerwill then be shipped fiat to the dairy. The dairyman will fold and gluethe bottom and will then dip the container in parafiin or the like; Thecontainer is then ready to befilled. After filling, the top will beclosed and sealed mere- 1y by applying heat and pressure to the sealingstrips 34 by any suitable means. Ordinarily the melted parafiin willafford a sufficiently secured closure Without the application of anyother fastener.

I away H1110 "impossible to clean g ass bottles by the methin one of theholes 37 If it is desired to pour out a large proportion of the contentsof the container, the second top layer 27 may be raised and the hole 36used. To empty the container entirely, the final top layer 26 may beopened.

There are many advantages in using a container of this k1nd, which maybe thrown after it is used. In the first place, it is more sanitarysince it is practically ods now in use with sufiicient thoroughness toremove'all dangerous germs or all traces of other substances which mayhave been put into the bottles. There is a great deal of expense inwashing milk bottles, resulting not only from the expensive washingmachines used, but from the labor involved. The delivery of milk inglass bottles necessitates the carrying of a great deal of surplusweight, not only in the delivery but in the return of the empty bottles.The collection of the bottles also requires a great deal of the driverstime.

The container to which my invention relates cannot be broken by thefreezing of the milk and will rarely be broken by dropping. The date offilling the container may be stamped thereon. Advertisements may also beprinted on the surface of the container. No deposit for the container isrequired when milk is bought at the store and there is no loss throughbreakage or from bottles which are not returned.

The provision of the raised bottom prevents possible contamination ofthe milk from contact with an unclean surface and the multiply bot omprevents possible leakage or breakage. The several top layers, two ofthem folding over one another from opposite sides of the container makea particular strong closure which will not be likely to open, even ifthe full container is dropped. These several top layers also provideconvenient means whereby either a small amount of cream may be takenfrom the container or a substantial part of the contents may be quicklypoured out if desired.

WVhile I have shown and described the con tainer in its preferred form,it is to be understood that the inventionin its broadest aspect is notlimited to a one piece container nor to the specific means by whicheither the bottom or the top are secured. It is to be understood,therefore, that the invention includes all such modifications as mayfall within the scope of the appended claims.

What I claim is:

1. A container of the class described, made from a one piece blank andcomprising five thence across the bottom of the container and thencedownwardly adjacent the opposite panel to the bottom edge thereof,thereby forming a peripheral downwardly disposed flange about the bottomof the container, one side of said flan e being five-ply, another sidethereof being our-ply, and the other two sides being three-ply.

2. A container of the class described, formed from a single blank andhaving flat side walls with integral continuations forming a top for thecontainer, said top being made up of a plurality of separate layers, theinner layer having an openin therethrough, the outer layer being imperorate and pro vided with means for forming a liquid tight seal for thetop.

3. A container of the class described having flat side walls, aplurality of said walls having integral continuations secured across.the top of the container thus forming a'top with a plurality of layers,of which the inner layer has a hole in it and the next layer has twosmaller holes directly above the hole in the inner layer.

4. A container having a top with more than two separate layers, theinnermost layer havmg a hole in it, the next layer having one or moresmaller holes over the hole in the inner layer, the outermost layerbeing imperforate and provided with means for forming a liquid tightseal for the top.

5. A container of the class described, made from a one piece blank andcom rising five panels folded to form four sides, t e two edge panelsbeing superposed to form a double side, said superposed panels and themiddle panel being extended and folded to form a three ply top, theinner ply having a comparatively large hole, the middle pg having twosmaller holes directly over the rst mentioned hole, the outer ply beingimperforate and sealed so as to be liquid tlght.

6. A container of the class described, comprising five integrallyconnected panels folded to form four fiat side walls, one side wallbeing double, and a raised bottom with a downwardly disposed flangeabout the periphery of the bottom, said flange having three or moreplies sealed together, each of the exposed plies of the flange at eachside of the bottom having an integral continuation extending across thebottom, whereby the container is rendered capable of holding liquids.

In testimony whereof I have hereunto signed my name to thisspecification.
